Seeing Black?

[LatinaVivit]

Okay I'm not too sure if this is related to puberty, but I'll give it a whirl.

So since maybe I was 12--I'm 16, almost 17 now--whenever I get up from laying down for an extended period of time everything I see starts to turn black and I lose sight completely. It's as if I'm about to pass out; everything turns numb and I get dizzy. Then, as quickly as it came, I get back to normal and feel fine. Any help?

P.S., I'm also 6'4"(195 cm) if that would affect it in any way.

Thanks!

that happens to me aswell, no idea why, i just carry on but i don't think it is size as i am quite small but am the same age as you aswell

Well not sure if it was the same but a few times it has happened to me...but only that once...told my mom and went to doctor said it was my sinus's that were full or something like that

Yes this happens to me, its a head rush, its just when you get up to quickly from sitting or laying from a long period of time. I don't know why it happens but it just does, nothing to worry about

[andrethaiss]

Maybe it has something to do with the circulation of blood in the head or something. Sometimes it happens to pilots, called a blackout but i dont know if thats the same thing. But it happens to me too.

See I thought it was head rush while reading this post. However, the loss of sight is a little concerning. Dizzy feeling/Sick feeling sounds like a head rush but the complete loss of sight is rather concerning.

I would suggest you perhaps talk to someone like a Doctor or even someone you trust as the bit about loss of sight is slightly concerning. However it could be a head rush it is just I have never had one where I loose sight.

This isn't puberty.

It sounds a little like what was asked in this (http://www.virtualteen.org/forums/showthread.php?t=144650) thread, and like some of the answers in that other thread suggests it could be because you're low on Iron. Are you often very tired and have low energy? Even if you're not it might be an idea getting it checked out anyway because if you do end up being anemic you can be prescribed iron to boost your stores. They should help if that ends up being the problem.

Also, unlike Derri, in my experiences with head rushes I tend to lose sight for about 10/20 seconds or so, makes it a pain walking down the stairs, right? :P I think most people's vision is temporarily gone when they have a head rush. I wouldn't say that was anything more concerning.

[flameprince]

this happens to me all the time. i just get up slowly.

[Idk what to put]

Happens to me all the time idk what causes it but I think it's ok as long as u don't actually pass out

[Silicate Wielder]

It's called headrush, I get it too. You can ask a doctor about it, but its probably normal, I could be wrong though.

Just to clarify. I meant if it was anything more than a few seconds and if it was happening very often. You should go see a doctor as if it happens a few times a month then it is nothing to worry about but if it is as bad as loosing your sight for a few seconds and is happening every day or every other day. You really should go to see your doctor as it might be something a little more serious.

If it is that, then you need to see a doctor as soon as

This was really helpful; thanks!

Damn Kyle beat me too it :P

Yeah Orthostatic Hypotension is fairly common. (Hypotension = Low Blood Pressure). Next time you are in your GP or near a Pharmacy ask them to take your Blood Pressure to see if it is low.

[norcaldude18]

This is very common especially in teens. I went to the doctor about this. He told me that it happens when your blood pressure is lower and cant get blood to your head fast enough. He said that it is also more common in taller people. His suggestion was to get my head closer to the ground as soon as that happens. Hope this helps. Oh and also drink more water throughout the day.

[dontfiguremeout]

Well does this happen anywhere else? Because if it does, you may want to see your doctor, because it can be caused by virdigo. But if you are still not sure what it is, maybe just talk to your parents or doctor to just check up to see what it is, because check up while something can just be starting, then find out later you have it, and it's gotten worse. And even if it was nothing, it's better you checked then not checking at all.

[candabear17]

I get this when I'm skating. It's more than likely from dehydration which is what I believe causes it for me but I also have an iron deficiency which may contribute. I'd say try drinking more water and if that doesn't help, talk to your doctor.
